cation.

This invention relates to journal bearings, and has for its object to providean improved anti friction bearing particularly designed.

for use upon an axle, although capable of use in other places if desired.

The object of the invention is to provide an improved roller bearing, the rollers being in the form, of the cylinders which-will give a long-or wide bearing upon the axle or shaft.

A further object of the invention is to provide improved means for holding the cylinders in spaced position around the hearing, by means of a retainer or spacing ring, as will more fully appear hereinafter.

The parts are so constructed that the boaring may be easily applied, and new rollers can be easily put in place should occasion arise. i Further objects. and advantages will ap' pear from thefollowing description and the accompanying drawings.

In the drawings, Figure 1 is a longitudinal section of the bearing as applied to an axle. Fig. 2 is a section on the line 22 of Fig. 1.

' Fig. 3 isa section on the line 3-3 of 1.

lteferring specifically to the drawings, a part of an axle is indicated at 6, and its journal or arm at 7, the latter being threaded at the end to receive a nut 8. The axle has a shoulder 9 with a'dust groove lOaround the same. The journal 7 is of uniform diameter throughout.

The axle box or casing comprises acylindrical shell 11 threaded at its inner end to screw into a ring 12 which has a shoulder 13 which projects inwardly toward the journal, between the shoulder of the axle and the end of the bearings. At its outer end the casing has an inwardly projecting rim 14 which serves to-hold the rollers 15 in place at the outer end, the shoulder 13 performing the same service at the inner end.

well as the'rollers.

The wall of'the casing or shell is reduced for a portion of its length, at the inner end thereof, forming a shoulder, as indicated at 16, and producing two diameters in the easing. A spacing ring}? fits within' the larger diameter and against the shoulder 16, said .ring having a circumferential series of openings 18 through which the rollers 15 extend, or in which they rest. These-passages 17 are openon the inner side, so that the rollers may 7 roject inwardly beyond the ring and into caring contact with the journal 7. The larger diameter of the box or casing 11 also receives a cylindrical thimble or bushing 19 which is placed within the box at a close fit, and which occu )ies the space from thespacing ring 17 to the inner end of the box. The thickness of the bushing 19 equals the depth of the shoulder 16,.so that the inner surface of the bushing is flush with the inner surface of the outer'end of the box, beyond the spacing ring. The rollers fit between the box so constructed and the journal which is thereby supported on the rollers and is'free to rotate in'the box with very little friction. The ring 12 holds the thimble in place, as The spacing ring 17 also acts as a retainer, since the openings through which the rollers cxtendarc somewhat more semi-circular, and consequently the rollers will not fall out laterally even if the journal be removed.

' To renew or replace a roller it is only necessary to remove the journal and take off the ring 12. The ends of the rollers are thus exposed, and can be grasped and pulled out endwise, and another roller qulckly inserted. The fact that the rollers are retained in position when the journal is removed is particularly advantageous for useon V6l11CleS,' in which the wheels often have to be removed from the axle for one purpose or another.

The rollers 15 are of the same diameter throughout and are in contact'with the journal along their entire length. This gives a very wide and strong bearing and. adapts the same for beavyuse.
